Abstract : The authors present a new protocol to perform non-interactive verifiable secret redistribution (VSR) for secrets distributed with Shamir's secret sharing scheme. They base their VSR protocol on Desmedt and Jajodia's redistribution protocol for linear secret-sharing schemes, which they specialize for Shamir's scheme. They extend their redistribution protocol with Feldman's non-interactive verifiable secret sharing scheme to ensure that a SUBSHARES-VALID condition is true after redistribution. They show that the SUBSHARES-VALID condition is necessary but not sufficient to guarantee that the new shareholders have valid shares, so they present an additional SHARES-VALID condition.
